That interrupt disabling in some cache flushes dates back further than
CVS history. Seems once uppon a time there was some CPU which didn't
like cache flushes with interrupts enabled. This is rather bad for
latencies so unless somebody else on this list recalls a good reason
I'd like to remove this.
